rms [s]=(1/T Ss^2t dt)^1/2

where T is defined to be the signal's period: the smallest positive number such that s(t)=s(t+T).

What is the rms value of the sinusoid s(t)=Asin(2πf0t)? (Again, write A as A and f0 as f0.)

**drwls**, Friday, January 25, 2013 at 7:11pmThe rms value of a sine function of amplitude A is A/sqrt2 = 0.70711 A.

That can be derived from the definition you were given.
